O believers! do not destroy your charity by giving reminders of your generosity and hurting the acceptors.― like those who spend their wealth to be seen by other men, but they believe neither in Allah nor in the Last Day. Their example is like a hard, barren rock, on which there is a little soil; when heavy rain falls on it, which exposes a bare stone. They will be able to do nothing with what they have earned. And Allah does not guide those who reject faith.
